Alarm Controls MCK-5-5WP Mortise Cylinder Key Switch, Stainless Steel, Left Entry, Green

Built for reliable access control, the Alarm Controls by ASSA ABLOY MCK-5-5WP mortise cylinder key switch delivers a durable, professional solution for commercial security and monitoring needs. The stainless-steel wall plate resists vandalism and corrosion while the left-entry configuration fits specific door orientations and retrofit jobs with minimal modification. Choose momentary or alternate action and SPDT or DPDT switching to match electric mortise locks, strike controls, or remote monitoring systems. The integrated green LED gives instant visual confirmation for operators and ties cleanly into surveillance and alarm workflows. For outdoor or exposed installations, the WP weather-resistant cover adds protection and reduces service calls. Mortise cylinders are sold separately for flexible master-key or restricted-key systems, and tamper-proof screws enhance physical security. Ideal for facility managers, integrators, and security professionals, this key switch simplifies control of doors, gates, and service access points while supporting monitoring, logging, and CCTV integration.
